JOHN A. RINGLEY, 0F PARKER, SOUTH DAKOTA.

WATER-TUBE BOILER.

Application filed September 29, 1922. Serial No. 591,237.

To all whom it may concern:

Be it known that JOHN A. RINGLEY, a citizen of the United States of America, residing at Parker, in the county of Turner and State of South Dakota, has invented new and useful Improvements in VVater- Tube Boilers, of which the following is a specification.

The object of the invention is to provide a water tube boiler of the flash or instantaneous type suitable for the effective generation of steam under conditions precluding the use of large boiler space and necessitating compactness, an extensive heating surface and large generating capacity as for example in connection with vehicles employing steam as the motive power; and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, wherein Figures 1 and 2 are side views from different positions of a boiler embodying the invention.

Figure 3 is a plan view of the same.

Figure 4c is a horizontal sectional view on the plane indicated by the line 44 of Figure 2.

Figure 5 is a detail view of one of the sections.

The boiler consists essentially of an annular base header 10 serving as a water distributing element and fitted with an inlet or supply water connection 11 and blow-offs 12, a series of sections 13, each consisting of upper and lower headers 14 and 15 connected by generating tubes 16, and a steam dome header 17 disposed transversely to the planes of the sections and in communication with the upper headers thereof respectively by means of nipples 18, said dome header being provided with a steam blow-off 19.

The end of the base header is provided at opposite sides with series of inwardly directed nipples 20 forming expansion joints with the terminals of the lower section headers and suitably packed as shown at 21 and fitted with gland nuts 22. The dome header 17 is provided with lateral nipples 2 1 for connection to supply conductors 25 for the transmission of steam to desired points. But one supply conductor is shown, however. The return conductor 26 is connected to the boiler in the plane of the base header.

A gauge cool: 27 is water level.

The arrangement of the sections which are disposed in close parallel relation and in a vertical position, with the lower header pipes spaced sufficiently to permit of the upward penetration of the flames and heat from the heating unit of whatever type may be employed in this connection, and with the upper headers of the said sections disposed in close relation to conserve and concentrate the heat in the space occupied by the vertical generating tubes, an economical utilization of the heat is effected, and dry steam may be drawn from the transverse collecting header 1? constituting the steam dome.

Moreover the arrangement of the sections facilitates the relief of the boiler of any accumulations due to the sediment or impurities by reason of the fact that the accumu lations thereof in the lower headers of the sections may readily be removed by the opening of the blow-off which is arranged in the base or distributing header with which the lower headers of the sections directly communicate.

While the above-described construction is referred to as relating to boilers of the flash or instantaneous type, and while in practice the structure set forth may be successfully used as a flash boiler, it is also peculiarly adapted for service as a quick acting boiler wherein a charge of water amounting at least to a half filling thereof is employed and which effects the rapid conversion of the water into steam by reason of the efficiency of the circulation and the comparative smallness of diameter of the vertical tubes which are exposed at all sides to the upwardly moving column of heat and flames from the burner or heating unit located beneath the same.

Having described the invention, what is claimed as new and useful is A flash boiler comprising an annular base header, a plurality of parallel sections each consisting of upper and lower headers and upright generating tubes connecting the same, the lower headers gradually diminisln ing in length in opposite directions from a diametral line on the base header and disposed in the plane of the base header and being terminally connected to the same, the upper headers being of diminishing lengths provided for testing the corresponding to the lower headers and havcommunication With said last named headers ing their ends free and unattached, the base at intermediate points in their lengths and header having diametrically opposed Water a steam delivery pipe connected to sand supply connection and blow-offs -'a "steam steam header.

- header arranged in diametrically spanning In testimony whereof he affixes his signarelation with respect'tothe base header and ture. at right angles to the upper headers and in JOHN A. RINGLEY.
